WELL CASING.

Application filed March 6, 1924. Serial No. 697,388.

This invention relates to well casings and has-for its object togenerally improve upon such struc-tures so as to provide a device ofthis nature having a sturdy, durable, and light structure which may beeasily assembled and which will be efficient in use.

Anotherimportant object of the invention is to provide sections of awell casing having associated therewith novel straining means. u

A still further object of the invention is to provide a well casingincluding a plurality of superimposed sections one of which is adaptedto be disposed in water and embodies a filter through which the watermust' pass to flow into the casing.

With the above and numerous other objects in view as will appear as thedescription progresses, the invention resides in certain novel featuresof construction, and in the combination and arrangement of parts as willbe hereinafter more fully described and claimed.

In the drawing:

Figure 1 is an elevation of the Well casing embodying my invention,`portionsthereof beine' shown in section.

Figurt 2 is a detail longitudinal sectlon through the intermediateportion D of the casing,

Figure 3 is a tranverse section taken substantially on the line 3-3 ofFigure 2 looking in the direction of the arrow,

Figure 4 is an elevation showing portions of the sections,

Figure 5 is a. detail transverse section taken substantially on the line5-5 of Figure 4 looking in the direction of the arrows,

Figure 6 is a transverse section taken o n the line 6-6 of Figure 4'looking in the d1'- rection of 'the arrows,

Figure 7 is a perspective view of the filter block,

Figure 8'is a perspective view of the housf ing for the iilter block,

Figure 9 is a longitudinal section through a modified form of thecasing,

Figure 10 is a transverse section therethrough taken substantially onthe lme 10-10 of Figure 9 looking in the direction of the arrows, and

Figure 1.1 is a detail perspective showing a portion of the modifiedform of' the casing.

Referring to the drawing in detail it will be seen that A designates theouter casing rwhich is extended down as far as water level B. The innercasing is-spaced from the outer casing and is formed from a plurality ofsections, The bottom section C is disposed below the Water. The sectionD is disposed above section C in superimposed relation thereto so as tobe positioned in the water. A section E is mounted on top ofsection Dand a' beveled section F is mounted 05 thereon. This beveled section Fisconnected to a pipe G of suitable length. The space above the section Eis filled with gravel as is shown at H and con-crete is poured on top ofthe gravel to fill the remaining space between the inner casing and theouter casing as is indicated at J. The sections of the inner casing areall joined together in the same manner preferably by the engagement ofthreaded extensions 5. tion C merely acts as a hollov.7 reservoir andalso as a foundation or anchor for the casing. Section D acts as afilter and embodies. a novel structure including the in- Secnercylindrical member 10 radiating from 80 which are the tWo series oftubes l1, one series being disposed adjacent the upper end andthe otherseries disposed adjacent the lower end. Corresponding tubs 11 of the tWOseries connect with housings 12 in which are 85 supported filter blocks13 having a plurality of slots 14 therein preferably extendingtransversely thereof. These slots are larger toward the inner face ofthe block 13 as is indicated to advantage in Figure 2. A band 15 issuitably lixcd to the collar 16 of a conical shaped member 17 thesmaller end of .which terminates in a collar 18 fixed' to the innercylindrical member 10. A pair of tubes 19 are fastened to the band 15and de- 95 pend therefrom as to be fastened to a lower band 20 uponwhich the housings 12 rest. As is shown to advantage in Figures 4 and 8tabs 22 are provided at the tops and bottoms of the housings 12 and arefixed to the bands 16 and 20. The filter blocks 13 are held within thehousing 12 by means ot I lips 23 at the tops and bottoms thereof whichare bent over upon the blocks as is shown to advantage in Figure 2. Thehousings are provided with side strips 24 which meet each other as isseen in Figure 3 and it is preferable to fill the space between thehousings and the inner cylindrical member 10 f with vconcrete orsimilarmaterial.

l n mounted upon the section F tends to divert Vthe gravel as it isbeing poured in the outer of the seztion F from the cylinder 26 and aninner cylinderl 27 the upper end of the outer cylinder converges andconnects with the inner cylinder. Section F is similar in constructionto section E except that the outer cylinder is tapered. A

The outer cylinder 26 of the section E forms .a protective casing toshield the inner conducting cylinder 27 from the pressure of the packedgravel H which isvfilled about this section. The outer tapered cylindercasing and likewise protects the lower end pressure of the gravel. L s

The modification of the invention Vshown in Figures 9, 10 and ll shows aplurality of sections held together by means of cables 30 which will beattached to the end sections by rivets 31 or in any other suitablemanner. Each section shown in this modification consists of an outercylinder 32 `and an inner cylinder -33. The inner cylinder is longerthan the outer cylinder and the exposed end is provided with apluralityof radiating fins or plates 34 which are connected to the outercylinder. The space between the cylinders is filled with gravel or thelike. From this construction it is obvious that a portion of the innercylinder 33v is exposed so that the water may be receivedl in the innercylinder through the openings.

.The sections embodied in this modification are preferably to beemployed upon wells of comparatively large diameter and used in place ofthe upper sections shown in Figure l indicated by the letters `F and G,above the 'water `line and ravel filling, above the sections C, D and d3which may remain of the type shown inthe preferred form in this figure.

I have, in the present instance, shown and described the preferredembodiment of my invention which will give in practice satisfactory andreliable results, and it is to be understood that the same aresusceptible of modifications in various particulars such as the detailsof construction, and the combination and arrangement of parts, withoutdeparting from the spirit or scope of the invention as hereinafterclaimed or sacrificing any of its advantages.

It is evident that this well casing is section having adapted to be usedwith a large variety of pumps and as such devices are well known 'in theart I have not shown any in the accompanying drawing. The device isparticularly adapted for use in water wells, but, of course, may beuseful in other wells and I do not wish to limit myself to theparticular illustration and the use mentioned here- 1n. t v

Having .thus described my invention, what I claim as new is:

l. A well casing section including a cylindrical core, avvconical shapedmember connected to the core, a band fixed to the conical shaped member,a second band, tubes concomprising a bottom section forming a'reservoir, a filter section arranged in vertically aligned position withthe reservoir a plurality of openings formed in the si e wallscommunicating with the interior thereof, the said section being ofassembled formation to permit replacement of the parts, a conductingsection disposed above the` filter section'and communi- (ating therewithprovided with an outer cylin rical casing assembled to provide a unitarystructure, and a plurality of con-v ducting sections communicating'withand disposed above the said last mentioned secseries of radiallydirected tubes connected to the conducting tube and to the housings andcommunicating therewith so as to conduct the water through the blocks tothe central conducting tube. Y

In testimony whereof I aiix my si ature.
